To all who/mitm@ concern. l

Be it known that I, WILLIAM RoRRIsON, a citizen of the United States, and a resident of Los Angeles, county ofIios'Angeles, State of California, have invented certain new and useful Improvements in Liquid-Samplers, of which the following is a specification.

The invention relates to devices which are employed for the purpose of taking samples of liquid from tank cars, storage tanks, or other containers at points below the surface of the liquid and preferably at the bottom yof the tank or container.

The object of the inventionristo provide a device which will take a correct samplel of Another object of the invention is to `provide a device which will take a correct sam-V ple of the liquid at any depth of the liquid.

Another object of the invention is to provide a device in which the sample may be` gaged without the necessity of pouring the liquid into another vessel.

The .invention possesses other advanta-l geous features,'which, Ywith the foregoing, will be set forth at length in the following description, that form of the invention which I have] selected for illustration in the-drawings accompanying and forming partof the presentl specification.` The novelty ofthe invention will be included in the claims succeeding Y.

said description. From thisit will be ap'-, parent that I do not limit myself to the showing made by said drawings and description, as I may adopt many variations within the scope of my inventionv as set forth in said claims.

Referring tosaid drawings: Figure v1 is an elevation of the device, showing the valve open; the chains being broken away 'to re' duce the size of the figure. Fig. 2 is a view of the bottom of the'device from below, the

valve being in the open position. Fig. Sis a i view taken on the line B-B Fig. 1, with the valve in the closed position. Fig. l is avertical section through the bottom of the device taken on the line A-A Fig. 3. Fig. 5 is an elevation of the lower part of the device showing one form of the means employed for Operating the valve at points above the bottom of the container.

The device is used for the purpose oftaking samples of liquid from containers below the level of the liquid therein, and is parwhere'I shall Outline in full ticularly adaptedy for sampling oil'in tank.. cars and storage tanks, although it may be use d for .sampling any 4liquid or substance which -will flow. *Tanks of Oil usually con` tam an amount of water and sludge which settlesk to the bottom of the tank, `and bylimeans of this deviceY the exact amount ofthe foreign matter in 'the tank may be' readily determined. -Thef device is -so constructed that it-maybe :loweredinto very close proximity to the bottom of the conf tainer so that a correct sample of the material at the bottom of the tank be obtained,for the devicemay be set so that it i will take a vsample atl any desired distance from-the bottom.

:The device consists of an open ended cylinder 2 of glass which will withstandfhot'.

liquids, which is `provided. at the top and f bottom with metal ends Y3--4 .which are held together by metallic rods `5.y Packing `orcushion rings 6 are arranged betweenthe ends ofthe cylinder and the metal ends to' -1 prevent a shattering of the glass. Secured. to the upper end 3 is a chain 22 or other flexible structure, byfwhich. the device is lowered into and withdrawn from the liquid,K the chain bein of suiiicientzlength toallow the device to e lowered to the bottom of. the container.

.'The metallic ends S-Qare substantially ring-sliaped'with theexception of the ears V.'' I

through which the rods 5 pass and areprovided with openings concentric with and.

substantially ofthe same diameter as-the.; cylinder, to permit the liquid to enter andv to. be discharged` from the. cylinder. The

movable valve-8 which controls the opening lower end 4f isprovided with-a transversely@ extending upwardithrough an ear in the f lower end 4. rIhe rod 9 is arranged parallel to the axis of the cylinder, so that the valve 13 by which it may beV i iioY moves transversely ofthe cylinder to open 0 0 atrip lever 15, which holds the valve in the open position. rlhe trip lever is fulcrumed on the lower end fl and the end thereof which does not engage the valve lies in the path of movement of the collar 16 secured to the vertically movable rod 17 which is arranged in ears upon the upper and lower ends 3 4. Secured to the under side of the lower end d is a stop 1S, beveled in accordance with the bevel on the valve, which stops the movement of the valve at the proper closed position.

Vhen it is desired to obtain a sample of the liquid at the bottom of a container, the valve is set in the open position and the device lowered into the liquid. `When the lower end of the rod 17 contacts with the bottom of the container, it remains stationary while the device moves downward, and the collar 16 coming into contact with the trip lever 15, releases the valve. The device is then drawn out of the liquid and the contents of the cylinder may be viewed. ln sampling oil, the cylinder will show a clearly deiined line between the water,

sludge and oil, so that by reference to a chart, the amount of water and sludge in the container maybe directly determined. By arranging the valve to swing transversely, the cylinder may be lowered into close proximity to the bott-om of the container before the valve is tripped, so that a sample of the liquid at the bottom of the container' may be obtained.

Attached to the upper end of the rod 17 is a chain 19 by means of which the valve may be tripped at any desired depth to obtain a sample or the liquid at that depth. When it is desired to obtain a sample at a given distance from the bottoni of the container, an extension rod 21 of the desired length is attached to the rod 17, preferably by screwing into the collar 16, and when this extension rod contacts with the bottom of the container, the valve is tripped. `When the device is to be used exclusively for taking samples from a point above the bottom of the container, the rod 17 may be made so that it extends below the collar the proper distance to trip the valve at the desired distance above the bottom.

I claim:

1. In an apparatus of the character described, a glass cylinder, metal ends arranged at the top and bottom ofsaid cylinder, tie rods extending through and connecting said ends, supporting means attached to the upper end, a transversely movable valve bearing a slotted lug arranged on the lower end of said cylinder, a lever adapted to engage said slotted` lug when said valve is in the open position, a vertically movable rod carried in said metal ends and a collar on said rod adapted to engage said lever and move it out of said slotted lug.

2. In an apparatus of. the character described, a glass cylinder, a transversely movable valve pivoted to said lower end, a slotted ear on said valve, a lever pivoted to the lower end arranged to seat in said slot to hold the valve in the open position, a vertically movable rod and a collar on said rod adapted to engage said lever and release the valve.

3. In an apparatus of the character described adapted to take liquidfrom containers, a transparent cvlinder, metal ends on said cylinder, a valve swinging transversely upon a stem, said valve bearing a slotted lug and adapted to be Dressed into its closed position by a. spring disposed on the said stem, alever .adapted to engage said slotted lug when said valve is in its open position, an actuating rod slidable in said metal ends and adapted to contact with the bottom of the container, and a collar on said rod adapted to engage and trip said lever to release said valve.

ln testimony whereof, I have hereunto set my hand at Los Angeles, California, this 27th day of February, 1914.
